I was just playing my Z-28 head when a loud crackling showed up. I went over to turn the amp volume down and it had no impact on the volume of the crackling. I'm assuming that it's a tube. I have a spare ef-86, 12AX7, and spare 6V6s, not sure if I have a spare rectifier on hand. Does the fact that the volume knob had no impact on the crackling narrow down which tubes I should swap out first? Thanks.
I would start with the EF86, then move on to the 12ax7. I would use the pencil or pen to tap the 6V6's to see if one of them is microphonic - that could save you from having to re-bias with the new 6V6's.

Thanks. I plan to put it on the bench today. I'll report results for future reference. It's probably due for a bias check anyway. I don't remember doing that when I bought it a couple of years ago from Mark (Basement Enthusiast) as it sounded fine out of the box.
Mine turned out to be one of the 6V6s also. Fortunately, I've had a lot of 6V6 amps in the past and have a bunch of really nice pairs in the tube stash. Not sure if I'm going to bother removing the chassis to re-bias right away or just play it and see how it sounds first. It's easy to be lazy.
GuitarZ: Thank You Z-Talk! I blew the dust off of my Signa Drive to plug in and was scratching my head on my old settings. I finally thought to do a search here and found a Z-Talk thread from 2011 with my settings. Nice!

GuitarZ: The Mrs jumped into action to find me a cancellation & called multiple spots. One said they had one now if the person didn't show up. She said GO! Went & got the shot. Called the Mrs. She says Where are you At? Went to the wrong one. Guess I don't listen.

j4gitr: Second Pfizer shot gave me a sore arm I felt sluggish, but played a couple hours of guitar with a friend, and ran an errand. Afternoon nap just about set me right.
